FATTACHMENTEOR srniiir-cn'rirnitsf To all whom it may) concern:

Be it known thatwe, DoUeLAsjKINznR and ALDEN KINZER, citizens of the .United States, residing at Ottawa, Salle and State of. certain new and useful lmprovements'in an Attachment for Stalk-Cutters, of which the following is a specification.

The present invention is designed as an improvement in seat supports for stalk cutsion rotary knives and unev road of travel. I I y 7 Another object of the invention is to pro vide a device of this character which is ap-. plicable to standard types of stalkcutters' and may be associated. therewith without making any material change in the cutter.

The above and other objects of this invention will be in part described and in part. understood from the following description of the presentpreferred-form of the inven- 1 .tion taken in connection with the accom-' w panying drawings wherein: Y i

Figure 1 is an elevational view of a seat.

supporting structure made in accordance I with my invention, a portion thereof being shown in vertical section and the seat per so being shown fragmentarily; i

Fig. 2, is a cross sectional view takenon the line 22 of Fig. 1 and looking in the direction of the arrow, 7 Fig. 3, is a similar view taken on the line 3--3 of Fig. l and looking in the direction,

of the arrow, and

wheel 4: being rotatably mounted upon the axle in the usual way. i i

Upstanding from the frame .5 is. the seat supporting post 7 preferably of a cylindrical configuration having one end 8 thereof reduced for engagement through .a f eorre-- sponding opening in tlie-apex ofthe frame 5 and secured from displacement bya cotter pin 9. A pair of abutment "lugs 10 are formed on the outer, periphery ofthepost 7 and are adapted for engagement with a, stop 11, which is formed uponthe upper end I of the frame 5. In this way the phase of in the county of La Illinois, have invented opening. 7

Fig. 4, is a fragmentary vertical sectional view.

" 1. seat support for stalk "direction.

Anintegralframe 12 consisting of a strap of metal is mounted on the post and has its ends bent downwardly and secured to per-f It is rnanent part 13 of the stalk cutter. understood that the post 7 is to be stationarily heldJin the frame 12; and in order to j i Specification of Letters Patent. Patgntefil lflay 10,1921, t j j Application filed. August 31, 192i Serial No. 407,201. i

augment this a second brace 14 is provided. I

' At'the point of the post 7 with which the brace 14: contacts a portion of said post is removal to provide a fiat side 15, the said a brace being provided with a corresponding through the frame 12andbrace 14 will be permitted although, as is obvious, rotary movement of said post independent of said "frameandbracewill be prevented.

.70 In this 'way vertical movement Anannulus 17 is formed on the outer pew) f ripheryof'saidpost directlyabove the up per terminal oftheflat side 15' of said post and remote from the upper'terminal of m i i i i the latter. Y convoluted on the upper end of said'post,

with, is a coillsprin'g '18, the upper end of jupper end .of said spring and has its lower above the annulus 17 but in contact there- 7 which extends beyond the upper end of the I end terminatedatga point'appreciably below I the upper end of the post. The ferrule consists of a metal sleeve. the upper end of which is provided with vertical incisions thereby producing segments which are bent.

relation to provide I I inwardly in overlapping a closed upper end 20. f

A seat 210i any desiredshape,

material is bolted to the closed upper end of securing means. .This; bolt also holds the segments of the ferrule together.

This seat supporting. structure is adapted to supplant the seats nowused on standard types of stalk cutters; andmay be conveniently attachedtheretowithout making material. changes over this invention as hereln described. The device of this invention is rear of the stub tongue and the axle of the rotaryknives of the stalk cutter. I

What is claimed is:

size or y v said ferrule 19 by a bolt 22 or other desired i cutters includ i ing ajpost, means engaging said post with r a permanent'part of the cutter framefand therein, a stop mounted uponsaid frame a permitting vertical but not rotatable movement of the'post, anda spring pressed seat mounted upon the post. 7

2. A seat support for stalk cutters ineluding a frame having ,a wheehmounted with said stop to limit the rotary movement of the post in said wheel frame, means connectin the post with a permanent'part of the cutter frame, a spring convoluted on theupper end of the post and extending upwardly therebeyond and a seat supporting [ferrule mounted up'onisaid spring. 7

In testimony whereof we aflix our signatures in presence of two witnesses.
